Chop the meats into 2-inch chunks or smaller if desired and marinate with the seasonings.
In a large pot, over low-to-medium heat, combine the oil, chicken and beef, and stir fry until the meat is brown on all sides. Add a bit of broth if the meat starts to burn or stick to the bottom.
Add the onion, peppers, sofrito, garlic, tomato sauce, bouillon, and green olives if using. Mix well and cover with water.
Once it comes to a rolling boil, add all the root vegetables, except the grated green bananas. Add additional water or broth if needed until everything is covered (approximately 1/2 inch over the root vegetables). Add the recao or cilantro on top, cover and continue to cook on medium-low heat for 20-30 minutes. Cooking times vary per stove, meat and root vegetable quantities. Keep an eye on it and stir occasionally.
Once the broth starts to thicken, try the broth and add additional seasonings to taste. Spoon in the grated green bananas and cook for an additional 10 minutes or until everything is cooked through and you achieve desired thickness. Keep in mind the broth will continue to thicken as it sits and cools down.
Remove the recao/cilantro. Serve and sprinkle fresh cilantro on top if desired.
Can be served with rice or on its own as a hearty soup. Enjoy!!
